| 摘 要： | 从LD泵浦固体激光器优化设计原则出发，设计了一种微型二极管泵浦激光器，并对种子激光器的结构和参数进行了优化。该激光器运转稳定，输出光束质量高，光束发散角小，光-光转化效率为17-4%，斜率效率可达24%，输出功率可达80mW。将此种子激光注入到调Q激光器中，改善了调Q激光器的输出特性，使得激光脉冲的建立时间缩短了40ns，输出的横模场分布得到了明显改善。 |

| Abstract: | According to the optimization principle for diode pumped laser, one kind of mini diode-pumped laser for seed-injection is designed. Using the numerical method, the optimized design is presented laser gain media, coupling system and resonant cavity. The seed laser beam from mini diode pumped laser was injected into Q-switched laser and output characteristics of Q-switched laser were studied. The experiment results show that this laser is stable, with high beam quality and small light beam divergence. The light light efficiency is 17.4% and slope efficiency is 24%. The output power of this laser is about 80mW. The buildup time of laser pulse in power oscillator decreases by 40ns and the injected seed laser field improve the distribution of output laser field． |
